Databasement before 1.10.9 Account Takeover via OIDC Email Auto-Linking

Summary

Databasement before 1.10.9 contains an authentication bypass vulnerability in OAuthService::findOrCreateLocalUser() that links OIDC identities to local users by email without checking email_verified. Attackers can register an identity provider account with a victim's unverified email to log in as any user, including the super-admin, and retain access after password resets.

Remediation

1. Inventory every David-Crty Databasement deployment, including staging.
2. Upgrade David-Crty Databasement to 1.10.9.
3. Confirm the running version after the upgrade.
